Problems solved by technology

[0002] Many sole materials on the market today have a beautiful appearance, but they will produce a bad smell after wearing them. The sweat in the shoes will form a humid environment inside the shoes, which will breed bacteria and produce a musty smell. For a long time, it will also cause foot disease such as beriberi

Embodiment 1

[0011] A kind of air-permeable shoe sole material, its composition and parts by weight are as follows:

[0012] 88 parts of EPDM rubber; 20 parts of carbon black; 22 parts of petroleum wax; 36 parts of polystyrene; 67 parts of natural 3L rubber; 8 parts of magnesium oxide; 11 parts of calcium zinc salt.

[0013] A method for preparing the above-mentioned breathable shoe sole material, the method comprising the following steps: mixing the above-mentioned raw materials in proportion, putting them into a banbury mixer for internal mixing, and then granulating the mixture after banburying through a granulator to obtain granules, and putting the granules into Cool in a sink, then dry at room temperature.

[0014] The main properties of the prepared material are as follows: tensile strength MPa: 20, elongation at break %: 580, permanent deformation %: 35, Shore hardness: 80, air permeability coefficient m 2 ·(s·Pa) -1 : 9.5·10 19 .

Abstract

The invention relates to an air-permeable sole material and a preparation method thereof. The air-permeable sole material comprises the following components in parts by weight: 88 parts of ethylene-propylene-diene monomer, 20 parts of carbon black, 22 parts of petroleum wax, 36 parts of polystyrene, 67 parts of natural 3L rubber, 8 parts of magnesia and 11 parts of calcium-zinc salt. The preparation method of the air-permeable sole material comprises the following steps of: mixing the raw materials according to the parts by weight, adding the mixture to an internal mixer for internal mixing, then granulating the mixture after internal mixing through a granulator to obtain granules, cooling the granules in a water tank, and drying at room temperature. By using the material provided by the invention, on the premise of not influencing the elasticity, hardness and other properties of the sole, the air permeability of the sole is greatly improved; and the material is nontoxic and pollution-free as well as safe and environment-friendly.

Description

technical field [0001] The invention relates to a breathable shoe sole material, in particular to a modified breathable shoe sole material and a preparation method thereof. technical background [0002] Many sole materials on the market now have a beautiful appearance, but they will produce a bad smell when worn. Musty smell, if it lasts for a long time, it will also cause foot disease of beriberi. Contents of the invention [0003] The object of the present invention is to provide a breathable shoe sole material and its preparation method, so that the breathability of the shoe sole can be greatly improved without affecting the proper elasticity, hardness and other properties of the shoe sole. [0004] The purpose of the present invention is achieved through the following technical solutions: [0005] A kind of air-permeable shoe sole material, its component and parts by weight are as follows: EPDM rubber 88 parts; Carbon black 20 parts; Petroleum wax 22 parts; Polystyr...
